This invention relates to foldable paper display cartons embodying areceptacle having a forwardly and downwardly inclined open top and acover therefor.

One of the main objects of the invention is to provide a display cartonof the type above mentioned having a cover which serves to build u thereceptacle so as to form a substantially rectangular .carton when thesame is in closed condition.

Another important object is to provide a cover structure which may beopened and adjusted so as to form a display for attracting attention tothe goods displayed in the open receptacle,

Still another important object of the invention is to provide animproved arrangement for locking certain of the overlapping flapportions .of the vreceptacle in folded, receptacle forming position.

Other objects and advantages will be understood by reference to thefollowing specication and accompanying two sheets of drawings wherein adisplay carton embodying a selected form of my invention is illustrated.

In the drawings:

Figs. 1 and 2 are perspectives of my improved carton showing the same inclosed and opened position respectively;

Fig. 3 is a section on the line 3-3 of Fig. 2,

Fig. 4 is a section on the lines 4 4 of Figs. 2 and 3,

Fig. 5 is a section on the lines 5--5 of Figs. 3 and 4,

Fig. 6 is a fragmentary section similar to Fig. 5 but showing certainparts as they appear' before the parts are completely folded,

Fig. 7 is a section on the line 7-7 of Fig. 5, and

Fig. 8 is a plan of the blank from which my improved carton is formed.

Referring now to the drawings, my improved carton comprises a receptacle10 and a cover 11 which are, in effect, hinged'to- `ether at the rearedge of the top wall of the cover and the top edge of the back wall ofthe receptacle. The hinge is formed by means of a crease 12 between thecover forming part of the blank and the receptacle forming part, thiscrease facilitating folding of the cover relative to the receptaclewithout tearing or breaking the paper. y

By reference to Fig. 8, it will be seen that the part of the blankforming the receptacle l0 is divided by crease lines (indicated by dotand dash lines) into various wall forming sections comprising a bottomwall 13, a back wall 14, a front wall 15 of considerably less depththanthat of the back wall, an extension `16 on the front wall 15 ofsubstantially the same depth as said front wall, a marginal portion 17foldable relative to the extension 16, side wall flaps 18-18 integralwith the back wall, tongues 19-19 at the free ends of the flaps 18-18,lips 20--20 projecting from the tongues 19--19 and flaps 21-21 integralwith the bottom wall 13.

The receptacle forming portion of the blank' may be folded along thevarious creases indicated to form the receptacle by first folding theback 14 upwardly at substantially right angles to the bottom wall 13,the flaps 21-21 upwardly at substantially right angles to the saidbottom wall, then folding the flaps 18-18 at substantially right anglesto the back wall 14 into position overlapping the aps 21 on the outsidethereof, then folding the tongues 19-19 at substantially right angles tothe flaps 18 and across the front edges 22-22 of the respective aps 21,and incidently folding the lips 2020-at right angles to the respectivetongues 19-19 so that the endsY 23--23 of the said lips will engage theinside of the inner iiaps 21 as clearly shown in Figs. 5v

and 6. Of course, it will be seen Athat thel lips 20-20 will be disposedon the inside of the bottom wall 13 of the receptacle and hence willoccupy'no material space in the receptacle while being effective toprevent outward unfolding movement of the flap 19 relative to the flap21. Hence, both Aflaps are effectively maintained in folded, mutuallyoverlapping position in which they form the end walls of the receptacleextending i between the back and front walls 14 and 15 respectively.

The front wall may then be folded upwardly, the extension 16 inwardlyand downwardly around th'e tongues 19-19 and the marginal portion 17inwardly along the' placement. \It will be understood that the tongues19--19 are prevented from unfolding from their folded osition asindicated in Fig. 5 inasmuch as t ey are embraced by the two-ply frontwall structure 15 and 16.

The cover formin portion of the blank shown inFig. 8 is ivided into wallforming sections by crease lines, a generally rectangular section 26constituting the top wall of the cover, a similar section 27constituting the front wall and iiap members 28-28 projecting from theends of the top 26 constituting side walls. For a purpose presently tobe explained, the top wall 26 and the flaps 28-28 are provided withaligned creases 29-29 which extend from spaced points intermediate thewidth of the top wall to the outer edges of the respective iiaps 28-28.The top wall 26 is also slitted as indicated at 30 to form a cut-outdisplay element, in this instance the cut-out element being more or lesskeystone shaped. -After the receptacle 10 is formed as above described,the cover part 11 may be produced by folding the front wall 27 and theside flaps 28-28 to a position substantially at right angles to the topmember 26 and then folding the top 26 along the hinge line 12 to theposition indicated in Fig. 1. By inspection of Fig. 8, it will beapparent that the front wall 27 of the cover is of substantially thesame depth as the back wall 14 of the receptacle. Hence, it will beunderstood that the front wall 27 will fit inside ofthe front wall 15 ofthe receptacle and will engage the bottom of the receptacle so as to becapable of supporting the top wall 26 in substantially parallel relationtol the bottom wall 13. In folding the cover to closed position as shownin Fig. 1, the front wall 27 first enters the receptacle inside ofv thefront wall 15 and the side flaps 28-28 of the cover subsequently enterbetween the side wall flaps 18 and 21 respectively of the receptacle 10.Thus it will be seen that the cover construction embodying the frontwall27 and side walls 28-28 may be considered extensions of the receptacleto close up the space between the narrow front wall 15 of the receptacleand the top 26 of the cover and between the inclined top edges of theside wall flaps 18 and 21 of the receptacle and the top wall 26 of thecover.

My improved display carton maybe used as a container for any desiredform of goods, such as canned or otherwise packaged goods, which aremore or less selfsupporting so that they will project above the narrowfront wall 15 of the receptacle and the forward narrow portions of therespective side walls. When it is desired to display the goods, thecover is opened up and the flaps 28-28 extended to flatwise position,whereupon the top 26 and the side aps 28-28 may be folded along thecreases 29 to theposition indicated in Fig. 2. By reason of the slit 30in the cover, the keystone shaped display projection 31 is removed fromthe rear portion of the top wall 26 and projects upwardly to increasethe atthe forward portions of the side flaps 28-28 extend beyond thesides of the receptacle' and constitute wing-like members '32-32 whichalso increase the attractiveness and which are adapted to be providedwith suitable illustrative or other advertising matter. The front wall27 of the cover is insertible into the receptacle between the back wall14 thereof and any contents in the receptacle so that the displayelements 31, 32 and 33 extend upwardly at the back of the receptacle asclearly shown in Fig. 4.

In the above description, I have used the term creases in a broad senseto indicate anysuitable form of fold lines which may be made simply bycreasing the paper to weaken the same along the desired lines, byscoring, or in any other suitable manner.

The above described display carton structure is quite simple, easy tomake and easy to fold into the closed carton condition illustrated inFig. 1 and also easy to open from such closed condition to the displaycondition illustrated in Fig. 2. I am aware that changes may be made inthe above described construction without departing from the spirit of myinvention, the scope of which should be determined by reference to thefollowing claims, the same being construed as broadly as possibleconsistent with the state of the art.
